Network Detection Policy Using Load Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current network detection and selection policies in wireless communications are overly simplistic and fail to utilize available information effectively, leading to inefficient resource usage and inadequate selection of appropriate networks, particularly in terms of load management and frequency band selection.
Innovation Solution
Incorporating load threshold and air-interface load threshold elements into network detection and selection policies, along with frequency band selection, to enable user equipment (UE) to make informed decisions based on WAN traffic load and air-interface load information, thereby optimizing network selection and load sharing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If network detection and selection policies are simplified for ease of implementation, then device complexity is reduced, but network selection precision and load management capability deteriorate
Solution Approach 1:
The network detection and selection policy is segmented into multiple independent threshold elements (air-interface load threshold, WAN traffic load threshold, backhaul load threshold) that can be individually configured and applied. This allows the system to maintain simplicity in implementation while achieving precise network selection through the combination of multiple specialized threshold checks.
2Measurement precision
If multiple load threshold elements are incorporated into network detection policy, then network selection precision is improved, but policy complexity and device processing requirements increase
Solution Approach 1:
The network detection and selection policy is designed to be dynamic, allowing thresholds to be adjusted based on network conditions and operator requirements. The policy can be updated remotely by network operators without requiring device redesign, enabling the system to adapt to changing network environments while maintaining manageable complexity through standardized update mechanisms.
3Productivity
If comprehensive load information is collected and evaluated, then network resource allocation efficiency is improved, but information processing requirements and energy consumption increase
Solution Approach 1:
The system implements partial action by collecting and evaluating only the most critical load information elements necessary for effective network selection (air-interface load, WAN traffic load, backhaul load) rather than attempting to process all possible network parameters. This selective approach achieves sufficient resource allocation efficiency while minimizing energy consumption and processing requirements on the UE side.

AI summary
An embodiment method for network detection and selection includes receiving, by a user equipment (UE), a network detection and selection policy including a load threshold element, the UE further receiving load information element from an access network (AN), and applying the network detection and selection policy to the AN.
